Cello, the best string instrument, creates beautiful music.  But how does a cello create sound?  Well, sound is produced by the vibrations of the string, and these sounds resonate inside the cello.  Cello strings are fifths (five notes apart) and each string creates their own frequency when you place your finger down on different parts of the string.  As you place your finger down the fingerboard to the bridge of the cello, it creates a higher frequency.  As you place your fingers up the fingerboard, it creates a lower frequency.  Each string has different frequencies because of the thickness/wavelength of the string.  The more thick/smaller wavelength the string is, the lower frequency the cello creates.  Additionally, cello's have harmonics on each of the four strings.  Each at a difference frequency and when you play the harmonic, it produces a loud clear sound.  When you play a harmonic, this creates a shorter wavelength which in turn produces a higher frequency sound.

It's cool to see the physics behind music. I really liked the waves unit last year and this is very interesting.
